- the superior sagittal sinus (SSS) appears slightly distended with lost signal void, demonstrating isointense to mildly hyperintense T1 and hyperintense T2/FLAIR signal intensity. Complementary MRV confirmed SSS thrombosis
- thrombosed cortical veins are seen at the high frontoparietal cortical sulci with linear bands of high T2 and DWI signal
- widened bilateral posterior parietal extra-axial CSF spaces
- no definite evidence of parenchymal metastatic deposits
- SWI/GRE fairly excludes subarachnoid or parenchymal hemorrhages
